Implements a very simple server that redirects traffic to https. One application of this (what it was created for) is an ECS service that works around the following ALB limitation (from http://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-load-balancing.html ):
Note
Currently, Amazon ECS services can only specify a single load balancer or target group. If your service requires access to multiple load balanced ports (for example, port 80 and port 443 for an HTTP/HTTPS service), you must use a Classic Load Balancer with multiple listeners. To use an Application Load Balancer, separate the single HTTP/HTTPS service into two services, where each handles requests for different ports. Then, each service could use a different target group behind a single Application Load Balancer.
